#26787: Access to deleted attribute triggers a query

This is a consequence of the implementation of #26207.
Now, all fields have a `DeferredAttribute` descriptor. This has the
consequence that this will trigger a model reload:
{{{
obj = MyModel.objects.get(pk=1)
del obj.title
obj.title
}}}
Up to version 1.9 (included), this code would raise an `AttributeError`.
Now it silently triggers a query to reload the field from the database.
Is this intended? If so, it should probably be added to the release notes.
